Kofa Mining District
The Kofa mining district lies in the southern part of the Kofa Mountains of central Yuma County (Figure 4). The name was derived from the contraction of "King of Arizona," the name of the most prominent and famous gold mine in the district. The mountains were earlier, and locally still are, called the S. H. Mountains, the initials reportedly being derived from various names such as Short Horn (Blake, 1893), Stone House (Darton, 1925) and another more vulgar name attributed to early soldiers or prospectors to whom the small peaks behind the larger spires resembled outhouses (Barnes, 1935). All government maps now use Kofa as the official name of the range.
The southern Kofa Mountains consist of a deeply and irregularly grooved, slightly sloping, mesa-like block with small flat-topped mesas, jagged spires, and other odd erosional forms. The western and southern edges present sharp, steep slopes while to the east, the topography is more subdued but still rugged. Numerous canyons and washes radiate out of the mountains on long, gently-sloping alluvial plains. Peaks and buttes rise to over three thousand feet in elevation in the range. A narrow, poorly-defined gap in the rocks separates the Kofa Mountains from the Tank Mountains to the south.

The mineralization in the Kofa district consists mainly of fine-grained gold and silver in quartz and brecciated wall rock with some local and minor copper and lead mineralization, and scheelite, in irregular fissure veins in the Mesozoic sediments. Considerable manganese oxides and minor fluorite also occur as gangue minerals. Some erratic and irregular manganese oxides have been prospected and mined in fracture zones in andesitic volcanics. Local, small, gold placers occur in the washes near the major gold mines.
The King of Arizona mine, the main producer of the district, was discovered in 1896 and was known as the Gleason before renamed, developed, and mined by the King of Arizona Mining and Milling Company. Blake (1898) gave a brief description of the early operations, noting the high grade values, up to some 40 ounces of gold per ton, in the upper workings. The mine continued operations to the middle of 1910 when economic ore played out in depth. Jones (1916) reported that the production of gold-silver bullion from the mine netted some $3.5 million dollars. The North Star Mine, a short distance to the north of the King of Arizona, was discovered in 1906 and worked by the Golden Star Mining Company from 1907 to mid-1911 when the profitable ore was exhausted. The recorded production of gold and silver from this mine was valued at about $1.1 million. Numerous other deposits of gold and silver with minor base metal sulfides have been worked through the years but produced, at best, only a few hundred tons of ore. Several ventures to reopen and work the King of Arizona mine have been unsuccessful. The tungsten and manganese operations resulted from the Government buying and premium price programs of the 1950s.
